To all whom it may concern: foration in the check-plate. The volatile oil Be it known that I, ALFRED A. ARNOTT, a passes through the supply-pipe 12, valve 8,

What I claim as new, and desire to secure by Letters Patent, is'-' 1. A hydrocarbon-burn er, comprising a tubular body member having a shank of reduced diameter at its lower end with a spiral shoulder formed by said reduction, and a vaporizing-tube wound spirally about said shank with the said spiral shoulder resting upon and engaging the whole of the upper coil of said vaporizing-tube, which tube projects laterally at its upper end from the said body member, and all of the coils thereof being below said projecting portion, all constructed and operating substantially as described.

2. In a burner, the combination with the tubular body member 1 having a shank 2 at its lower end of reduced diameter with a spiral shoulder formed by said reduction and a bore therethrough with a gauze cap 5 covering the upper end thereof; of a vaporizing-tube ber with all of the said coils below said projecting portion and the other end of said tube projecting downwardly substantially parallel I with the axis of said body member and thence upwardly substantially parallel with the said downwardly-projecting portion and terminating below the bottom of the body member; and a perforated check-plate 10 covering the end of said tube; and a nut threaded thereon inclosing the said check-plate, all constructed and operating substantially as described. In testimony whereof I affix my signature in presence of two witnesses.
